WSL Syntax Error near unexpected token curl install script

changed title from WSL Syntax Error near unexpected token curl install scrip to WSL Syntax Error near unexpected token curl install script

I can't reproduce on Linux (currently no WSL), but it could be that the -s (silent option) helps. Eg,

curl -s https://dl.openfoam.com/add-debian-repo.sh | sudo bash

Strangely enough, this is actually what the usage inside of add-debian-repo.sh says, but the wiki doesn't. So maybe need to update the wiki?

If that still doesn't work. Then try it as a two-stage process. First curl (or I actually like wget) to grab the file and then feed it to bash. It should be the same as directly piping it, but at least this way you may get a better idea of what is going wrong.

It seems like I have potentially multiple issues going on, first with my wget and curl operations:

I expected the output of the curl to be the add-debian-repo.sh script, but it seems like instead I am just getting the HTML code for the page. Is there a step that I am missing to get that file? I'm also a bit perplexed by the permission error on the wget, but this may be the root of my problems with WSL.

Trying to separately download the shell script and run from inside WSL I get the following GPG key error (not sure if that's related to the wget error or not):

sudo bash add-debian-repo.sh
Detected distribution code-name: noble
Added /etc/apt/sources.list.d/openfoam.list
Importing openfoam gpg key... gpg: no valid OpenPGP data found.
Error
Failed to add /etc/apt/trusted.gpg.d/openfoam.gpg

Apologies if this is the wrong forum for this, and let me know if I should instead move this over to WSL issues. The help is much appreciated!

Hi,

I have tried to reproduce the error and did not succeed. With -s, without it, everything works as expected.

Since there is HTML code, maybe reporter is behind captive portal of a WiFi network? This can explain HTML instead of bash script, the same HTML is written to GPG key, which is refused by gpg command.

I'll close out since nobody else seems to have this happening (makes it difficult to trace). I think that @alexey's guess sounds about right.
